The National Weather Service issued a flash flood watch this morning for Kauai and a flood watch will be posted for other islands later today.

A "potentially dangerous weather situation continues to develop today as a cold front approaches the state from the west," forecasters said. "Moist and unstable atmospheric conditions ahead of the cold front will affect Kauai County today and spread to the rest of the state by this evening."

Heavy rain and thundershowers as the weather system moves across the islands through tomorrow.

The weather service also issued a special marine warning this morning for the Kauai Channel because of gusty winds, higher seas and reduced visibility because of heavy rain.

A high surf advisory remained in effect for north and east facing shores until this evening because of a declining swell with wave faces on the north shore of 10 to 18 feet and east shores of six to 10 feet.

The weather system should leave the islands before the Honolulu Marathon Sunday morning, forecasters said. Runners can expect normal tradewind weather for the event, and may expect some clouds and showers.

A flash flood watch means that conditions may develop that lead to flash flooding, and the public should pay attention to the latest forecasts, the weather service said.

The Big Island summits may see a mixture of snow and rain as early as tonight and last through Saturday. Precipitation may be heavy at times.
